UPDATED STORY:
Sheriff's deputies believe they know who murdered 18 year old Tyler Mike.
A 17 year old is now accused of shooting and killing Fannie Admore's nephew.
"God is not sleep. I told my husband 'before the night is over, they will have somebody," Admore says. "If you big enough to pull the trigger, be a man and stand up and own up to it."
Sheriff William Snyder says a witness saw the shooting in the Booker Park neighborhood.
He says both the suspect and victim were apparently meeting up there aground 9 Thursday night.
It's not clear why.
"[He] came up on a bicycle, and while he was sitting on the bicycle actually opened fire on our victim," Sheriff William Snyder says.
Mike's body wasn't found until around 7 Friday morning by a school bus driver.
Friends are trying to make sense of the violence.
In a small town like this, Veronique Trimble says every loss hits hard.
"It actually touches home," Trimble says. "It's not like it's someone that you don't know, it's someone that grew up with your kids, someone that comes to the local churches."
Trimble says the potential loss of innocence is also devastating.
Several kids in the neighborhood witnessed Tyler's body lying in the road Friday morning as they made their way to school.
"To wake up that morning, and my daughter walks past to head to her bus stop, and to say 'Mom, I seen him laying on the ground'…now that's going to affect my child," Trimble says.
That 17 year old is being charged with first degree murder.
He will be transported to the juvenile facility in Ft. Pierce to be processed, and then return to the Martin County Jail.
The sheriff says his resource officers will meet with school officials to offer counseling to the kids who saw the body.
It's News Channel 5's policy not to name a juvenile arrested for a crime unless that person is charged as an adult.
